This invention relates to improvements in a bracelet clasp for ornamental use; especially bracelets to be worn upon the wrist as an article of jewelry.

An object of the invention is to provide a bracelet clasp of :such constructiontha't'the links thereof 'canbe permanentlyconnected to one another and-yetpermit the*bracelet to be enlarged so that it can be slipped over the hand upon the wearers wrist and then shortened-to keep it in position. f t The nature and advantages ofvthe' invention are fully set forth in the following description taken with the accompanyingdrawings, Whereon a preferred embodiment of the invention is illustrated/ This disclosure how ever is explanatory only,1and.I may. vary the shape, size and arrangement of the. parts without exceeding the scope and principle of Fig. 2 is a similar view showing the same as defined inthe: appended parts of a bracelet about to be extended tov make the bracelet larger; v

Fig. 3 is a bottom view of the bracelet with in fully extended position Fig. 4 is a section on the line 4& of Fig. 3; Fig. 5 is a section onthe line- 55 of Fig.3; Fig. 6 is a section on the line 6-6of Fig. 3; Fig. 7 is a section on the line 7-7 of Fig. 3 Fig. 8 is a cross section on the line 8-. 8 of Fig. 9 is a similar section on the line 9-9 of Fig. 3, and

Fig. 10 is a section on the line 10-'10'of Fig. 3.

The same numerals identify the same parts throughout. i The bracelet .is made up of a number of short links 1 secured together by means of pivot pins 2 and these links maybe'of any desired construction. Enough of the links 1 will be included to make a bracelet of the desired length, all joined together and the terminal links 1 will be united by larger links BRACELET- o Asrj 1 1928; Serial No. 274,768.

indicatedat-3, 'and 5which can be extended to make the bracelet bigger 'as shown in Fig. 301' foldedtogether as shown in F i'g. 1. For this purpose, the links '3, 4: and 5 are so designed thatthey have interfitting engagementwith one another. :The link 3 has the form of an inverted trough;-the link 7 4: (consists of two strips perforatediat their endstobe pivoted to the link 3 andthe link-5 and the link 5 may be in theforni of'a closed tube which' is rectangularin shape. These 7 three links; *5, 4 and'SiareilIustrated in cross section on Figs 8,9 and 10 respectively. Thus,'all of 'thelinksi, 3, land 5 are pinned together and the braceletis put on by making fit-larger and then shortening it to -be worn 1 around the wrist; and to remove it the. links '3, 4: and 5 need only be distended.' Hence, no catch-is required. i f j Thelink 3 having the formof an inverted trough is provided with a top 6 and sides 7 with one end 'thereof closed as indicated at 8. This end maybe'cut along the sides. and then punched orstamped'out to provide an open ended hollow projection 9 to serve as abearing for thepin 2 which'connec ts'it to the adj acent link 1; All of the pivot pins 2 may be tubular with their ends expanded'to keep them"in place. ,The sides ofthe adjacent link lmaybe rounded'as indicated at 10 and the ends of'the sides 7 of thelinkB may-be recessed .to: form seats as at 11'ton1atch with the rounded ends 10' of the link" 1. "-Each of i the 'links 1 may be shaped in'cross section so i as to be somewhat similar to thelink'3: and across the bottoms of these links may be connecting bars'12. 'Atthe'opposite endof the link 1=j oined'to thelink 3, are perforated pro-' jec'tions 13to enable itztobe united by a pivot pin 2 to the adj acentlinki This adjacent link may likewise have its ends rounded and the ends of said link 1 which. are adjacent the projections: 13 may also be recessed in the same way'as the sides of the link 3.

The opposite endof the link 3 will be open asshown at 14 and the sides thereof mayalso' be'recessed as shown at 11, and the two parts of the link 4 will enter the open end ofthe link 3 and be united thereto by pivot pins 15 which may be eyelet rivets. These rivets may receive in their outer ends, knobs 16 preferably held in place by solder to add to the ornamental appearance of the bracelet.

At their opposite ends, the two parts of the link 4 will be pivotally united to the .link 5 by means of pin 2. This link 5 comprises sides 17 and a top and bottom 18, and the sides 17 are extended somewhat and rounded as indicated at 19 where they are united to the link 4. At the opposite end, the top of this link may be extended and bent to form a tubular bearing 20 so that it can be joined by a pivot pin 2' to the adjacent link 1, the bearing 20 being received between the rounded ends 10 of the sides of this link 1.

All of the links 1, 3 and 5 may be curved somewhat and when the links 3, 4 and 5 are to be folded'into one another to shorten the bracelet, the two parts of the link 4 are first caused to enter the link3 and be housed thereby; passing into this link through the open bottom. Then the tubular link 5 follows and both links 4 and 5 .are completely enveloped by the link 3; one endof the link 5 then projecting from the open end 14 of the link 3 and being there attached to the adjacent link 1. The bracelet then has the form of-acomplete loop encircling the wrist snugly instead of having two ends to be joined by a catch and can be removed by enlarging it merely by taking hold of the two small knobs 16 and pulling upward to get the links 3. 4 and 5 in a position to be distended as indicated on Fig. 3. The curvature of the link 3 is such that the outer surface of the bottom of this trough-shaped link, that is, the part or surfacewhich will be uppermost and exposed when the bracelet is worn, is convex.

The construction is thus quite simple,'while at the same time the parts are securely united and there is no liability of the bracelet getting out of order. 7

I claim V 1. A clasp for a'bracelet comprising a plurality of links pivotally connected together, one of said links having the form of an inverted trough with one end closed and a bearing at said end for a pivot pin to enable it to be connected to one end of the bracelet, the other end of said trough shaped link being open, another of said extensible links having the form of a pair of strips which enter the open end of the trough shaped link and are pivotally united thereto, and a third extensible link having the form of a rectangular tube, the end of which is received between the two strips of the second-named extensible link and is pinned thereto, the opp0- site end of the tube shaped link being pinned to the opposite end of the bracelet, the extensible links being adapted to be folded together so that the strips of the second link are received into the trough shaped link along the sides thereof and the tube shaped link is housedin said trough between the strips of the second named link, the trough shaped link having knobs adjacent its open end to enable the trough shaped link to be pulled preparatory to distending the links and enlarging the bracelet.

2. In a clasp for a bracelet, consisting of connected links adapted to be extended to enlarge a bracelet, one of the links comprising a housing having spaced parallel side members, a second link in the form of a rectangular tube, two parallel oppositely disposed strip members, pivots connecting the strip members at one end with one end of the corresponding side members and at the inside faces thereof, a pin passing through the opposite ends of the strip members with one end of the tube fitted between the strip members, and knobs associated with said pivots, extending laterally beyond the side members and adapted to be grasped in operating the connecting links.

In a clasp for bracelet, a box-like link having a protruding bearing connection at one end with the bracelet,.a pair of parallel oppositely disposed strip members embracing at one end the opposite end of the box-like link and pinned thereto for pivotal movement, a housing including parallel oppositely disposed side members having seats in the end edges thereof, an individual pivot 9 connecting theopposite end of each of the strip members with the corresponding side member adjacent the end edge seat thereof, thereby leaving between the strip members an unobstructed space, said strip members being foldable in the housing between the side members and said box-like link being foldable between the strip members to occupy said unobstructed space and permit said bearing connection to be received in said end edge seats.

In testimony that I claim the foregoing as my invention, I have signed my name hereto.
